Objective:
Post-stroke neurocognitive disorders are highly prevalent, yet screening tools that are fit for culturally diverse populations are scarce. This study evaluates the impact of cultural differences on the Oxford Cognitive Screen (OCS), a stroke-specific screening tool.
Methods:
To evaluate cultural differences, we compared two populations with varying degrees of cultural diversity and Western, Educated, Industrialized, Rich and Democratic (WEIRD) characteristics. We adapted the Dutch OCS for Suriname through a multi-stage process. Using Bayesian hierarchical regression analysis, we compared 264 Surinamese participants, assessed with the adapted Dutch OCS, with 247 Belgian participants, assessed with the Dutch OCS, while controlling for age and education. We further investigated whether the associations of age and education with performance were comparable between the two populations.
Results:
Our findings revealed minimal differences in OCS performance between the Belgian and Surinamese populations. Both populations showed similar age-related decline and education-related improvement across all subtests, except for Picture naming, where the age-related decline was more pronounced in the Belgian population.
Conclusion:
These findings suggest that with minimal adaptation, the OCS is a viable tool for screening post-stroke neurocognitive disorders in culturally diverse populations.

Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this;...

Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...

01:21Cognitive Learning
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...
